This is one of the most beautiful chapters in the Bible. Along with Ecclesiastes 11, and a few verses out of Ecclesiastes 10, we have here Solomon's conclusion. He had found his way out of the doubts and perplexities that for a time had confused him; and here (in these passages) he thunders the great doctrinal teachings of God's Word.
So great is the importance of this chapter that we shall study it one verse at a time.
Ecclesiastes 12:1
Remember now also thy Creator in the days of the youth, before the evil days come, and thou shalt say, I have no pleasure in them
